Thank you for reading this.
I'm working my way through a series of exercises where the author only
provides a few solutions.
The reader is asked to modify the histogram example so that it uses the get
method thereby eliminating the if and else statements. Histogram2 is my
effort.
The resulting dictionary only contains the default value provided by "get"
and I cannot see how the value can be incremented without an if statement.
You are almost there. Note that all you have to do is increment 1 to
the current 'value' for the key denoted by c. If you change the line
with get() to the following, it works as you want it to:
d[c]= 1 + d.get(c, 0)
Output:
{'a': 1, 'b': 1, 'o': 2, 'n': 1, 's': 2, 'r': 2, 'u': 1, 't': 1}
histogram2
{'a': 1, 'b': 1, 'o': 2, 'n': 1, 's': 2, 'r': 2, 'u': 1, 't': 1}
You were almost there. Good Luck.

Thanks Amit and Mitya,
I thought I must have been close.
I've played with C++ since the mid 90s and I'm finding Python very
refreshing.
